针对一类非线性广义系统，提出了基于模糊模型的伺服控制方法。在我们以前的论文中，伺服控制的基础上提出了使用误差向量和输入差的误差动态。本文将伺服控制技术推广到非线性广义系统。广义系统比典型的状态空间模型能代表更大类的非线性系统。给出了用于伺服控制的模糊广义系统的构造方法，并以线性矩阵不等式（LMI）的形式导出了模糊广义系统的伺服控制器设计条件。此外，还讨论了适用于目标点切换的伺服控制。设计实例说明了这种方法的实用性。
This paper presents fuzzy model-based servo control for a class of nonlinear descriptor systems. In our previous paper, servo control based on error dynamics using error vector and input difference was proposed. In this paper, we extend the servo control technique to nonlinear descriptor systems. The descriptor system can represent larger class of nonlinear systems than the typical state-space models. We show the construction method of fuzzy descriptor system for servo control and derive servo controller design conditions for fuzzy descriptor systems in the form of LMI. Moreover, the servo control which is applicable to switching of target point is also discussed. Design examples illustrate the utility of this approach.
